The geochemical features of a thermokarst lagoon were compared with two thermokarst lakes on the Bykovsky Peninsula in northeastern Siberia. This data set includes pH, major cations and anions, alkalinity, salinity, and dissolved iron (ferric and ferrous) concentrations from porewater of lake and lagoon sediments; the concentration and stable isotopic signature of CH4 in small plug samples from the sediment cores; total carbon (TC), total organic carbon (TOC), total nitrogen (TN), and total sulfur (TS) measured from the bulk sediment; and several biomarker indices (e.g. CPI, Paq) were calculated based on n-alkane concentrations to characterize the origin of organic matter (OM) in the lakes.
Samples were taken from Bykovsky Peninsula, southeast of the Lena Delta in the Buor-Khaya Gulf of the Laptev Sea in northeastern Siberia, Russia, during the field expedition in April 2017. Three cores (PG2420, PG2426, and PG2423) were retrieved from Lake Golzovoye (LG), Polar Fox Lagoon (PFL) and Lake Northern Polar Fox (LNPF), with drilling depths from the sediment surface of 5.2, 5.4, and 6.1 m, respectively. 129.302 129.343 71.7453 71.7518 Helmholtz Young Investigators Group VH-NG-919 German Ministry of Education and Research 03G0836A, 03G0836D, 03F0764A, 03F0764F ERC PETA-CARB 338335 HGF Impulse and Networking Fund ERC-0013 DBU grant Characterisation of organic carbon and estimation of greenhouse gas emissions in a warming Arctic
